LOCK.

To all whom it may concern:

Be it known that I, JOHN H. SHAW, a. United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

particularly to locks in which a pin tumbler lock mechanism is housed in a knob, and

wherein both the knob and the pin tumbler such as alatch bolt. The pin tumbler lock is operative on the bolt at all times when the proper key is used, but the knob may be dogged by suitable mechanism in order to fine operation of the bolt from the outsideto the key mechanism alone.

I-Ieretofore the pin tumbler lock mechanlsm has usually been rigidly, connected with the knob shell so as to rotate therewith when the knob is turned, and the pin tumbler lock is secured to the escutcheon, or to the casing containing the bolt mechanism only through the intermediary of therotary knob spindle. By

ever, the pin tumbler lock is rigidly and fixedly secured to the escutcheon just as in the case where no' inclosing knob is emplayed, and the knob, or at least the inajor portion of the same, rotates about the pin tumbler lock, on which it has a suitable bearing.

The primary objects to provide an eflicient knob lock constructed along the lines above indicated; to furnish a structure in which the cap piece of the knob contains the pin tumbler lock and is fixed tothe escutcheon to form abearing for the rotatable part vide a construction in dle holds the key rod in place relatively to the key barrel or plug; to furnish a lock in which the means for securing the pin tumbler lock to the escutcheon also serves to secure the knob thimble to the escutcheon; and to generally improve the construction and operation of devices my invention relates.

Fig. 10 is a rear elevation of Fig. 9, and Fig 11v is a detail of the thimble. Referring to the drawings, my improved knob comprises in its general featuresa cap piece carrying the pin tumbler lock 21 and fixed to the escutcheon 22; 23 forming the majorportion of the knob proper, and rotatable about, and having a bearing on, the cap piece 20; a spindle 24 carried by the knob fixed to the escutcheon and through which said spindle extends. The pin tumbler lock -21 comprises a casing 26 secured to, or integral with, the cap piece 20, and it is likewise provided with a pin tumbler extension 27, and with a key plug 28, which rotates in an opening in the cap piece. sides of the casing 26 of the pin tumbler lock, the latter is provided with rearwardly projecting lugs 29, having screw holes 30, screws 31 screwed into' the pin tumbler lock and fixing it rigidly to the escutcheon 22, as shownin Fig. 5. The screws 31 also pass through openings 32 in a fia11ge33 at the outer end of the thimble 25, and the heads 34 of said screws are located at the inner face of the escutcheon, with theshanks of the screws passing through holes 35' in the escutcheon, whereby the pin tumbler lock and the thimble are both rigidly secured to fixed bearing for the correspondingly shaped front edge 23 of the knob shell 23, which a knob shell:

At opposite 6.0 the cap or disk 47 extends, and in which-it is seated in the manner shown in Figs. 4 and 5.

the portion of the pin tumbler lock extending rearwardly from the cap piece. The shell 23 is connected with the knob spindle 24 by a flange or web 36, which preferably joins the shell and the spindle in an in tegral manner. The web or flange 36 is interposed between the flange 33 of the thimble and the rear end of the case of the pin "tumbler lock, and is provided with arcuate slots 37 which clear the lugs 29, and permit the knob to have a limited turning movement. By referring to Fig. 6, it will be noted that the lugs 29 and slots 37 are tumbler lock and the thimble to the ing plate 39, groove 40 in shaped to conform to each other, but that the lugs are considerably shorter than the corresponding slots. In the normal position of the parts, as shown in Fig. 6, the lugs will be in the middle portions of the respec-,

tive slots so" that the knobshell may be turned to a certainv extentin either direction The'screws 31 not only attach the pin escutcheon, but they also secure the knob spindle 24 rotatively in an opening 38 in the escutcheon by clamping .against the inner face of the escutcheon the'sectional retainwhich extends into an annular the knob shank, as shown in Figs. 4 and 5. 1 The inner end ed to-fit a corresponding polygonal opening in a hub orro1lback*42, whereby the bolt (not shown)--is adapted to be retracted in any preferred manner. Adjacent the rollback 42 is a. second roll-back 43 adapted to be operated by the pin tumbler lock, for

which purpose said roll-back 43 is suitably connected to'a key rod 44 extending rearwardly from, and: rotatable by the key plug 28. The outer end of'thekey rodlis provided'with ahead 45, which is detacliably connected with the keylug preferably. 1n

A full rotation of the knob'shell, however, is prevented by the engagement of the lugs 29 with the edges of the respective slots 37 The cap piece 20 of the knob and he p1n tumbler lock remain stationary at all times. Whentheknob spindle 24 is rendered immovable, the lock may be actuated by a key inserted in the keyway of the pin tumbler lock, and adapted to release the key plug, which, in turning, will operate the key rod and itsroll-back in an obvious manner; The facility of manipulating the knob is not impaired by having the section 20 thereof stationaryv as the movable part is so located as to be readily grasped and turned.

v The knob shell is so'assembled relatively to the pin tumbler lock as to hold the key rod in operative relation to the latter. The main parts of the structure may be readily detached by removing the-screws 34 from the inside of the escutcheon, and disengag ing the retaining plate 39 from the knob be imme- The lock escutcheon will hold the parts firmly to- Of ourse, I have not attempted to illustrate or describe the various modifications of the. construction which may be adopted within the scope of the appended claims.
